The former Republic of Ireland international was granted extended leave to be the best man at his brother’s wedding in Europe and consequently missed the recent friendly against Manchester United at Optus Stadium.

Keogh, who was the club’s leading scorer last season with 15 goals, reported for training on July 14 but the club has yet to put him through the mandatory medical screening that must be completed before a ball is kicked.

By contrast, players who arrived in Perth after Keogh have been medically signed off and are training as normal.

Eyebrows were raised when the 33-year-old was dropped for the A-League Grand Final which Glory ultimately lost to Sydney FC on penalties in May.

Despite interest from other A-League clubs, Keogh agreed a new deal to remain in Perth for another year and he will become an Australian citizen in the next few weeks.

Meanwhile, Glory are believed to be trialling a left-sided Asian player as they look to replace Jason Davidson who departed for Korean giants Ulsan Hyundai last month.

New recruits Bruno Fornaroli, Jacob Tratt and Nick D’Agostino should all feature against the Wanderers, and Popovic could again give game time to his sons Kristian and Gabriel following their cameo appearances against Manchester United.
